| 20080268815 | Authentication Process for Access to Secure Networks or Services - A system (and a method) are disclosed to access to secured services that are located behind a firewall. In one embodiment, the system receives at an authentication server a request to access the secured services. The request includes an identification of a mobile telephony device. The system transmits the identification of a mobile telephony device to a mobile telephone network server. The mobile telephone network server generates and transmits at least one security challenge that is forwarded to the mobile telephony device. In response, the mobile telephony device generates at least one response to the at least one security challenge, which gets forwarded to the mobile telephone network server. The mobile telephone network server notifies the authentication server if the response has been appropriately verified, and if so, the system allows the authentication server to allow access to the secured services, e.g., through an authenticated session. | 10-30-2008 |
| 20090156253 | Apparatus and Methods for Providing Fully Qualified Domain Name Resolution for Home Network Realm Based on International Mobile Subscriber Identity - Various embodiments for providing fully qualified domain name (FDQN) resolution for a home network realm based on an International Mobile Subscriber Identity (IMSI) are described. In one embodiment, a mobile computing device may be arranged to retrieve an IMSI including a Mobile Country Code (MCC) and a Mobile Network Code (MNC) and to derive an initial FQDN from the IMSI using an initial MNC rule.

| 20120033563 | PACKET CLASSIFICATION AND PRIORITIZATION USING AN IP HEADER IN A MOBILE WIRELESS DEVICE - A method and apparatus for packet classification and prioritization using an internet protocol (IP) header in a mobile wireless device. The mobile wireless device includes an application processor and a transceiver. The transceiver in the mobile wireless device receives a higher layer packet from the application processor and reads a value of a field embedded in the higher layer packet. The transceiver creates at least one lower layer protocol data unit from the higher layer packet and maps the at least one lower layer protocol data unit to a wireless access channel having a quality of service property. The mapping of the lower layer protocol data unit is based on the value of the field read by the transceiver.

| 20120033612 | METHODS AND APPARATUS FOR REDUCING DATA TRANSMISSION OVERHEAD - Methods and apparatus for reducing data transmission. In one embodiment, rather than immediately transmitting first data, a first device postpones opening a data connection; any subsequently arriving data is queued with the first data, and transmitted together. Connection overhead is optimized by delaying connection establishment until it is necessary, and in some cases eliminating idle mode operation altogether. Stochastic embodiments are also disclosed for adjusting transmission behavior to maximize one or more desirable outcomes. For example, one such embodiment queues data for a stochastically determined period of time, prior to opening a data connection. The stochastically determined time interval balances the likelihood of efficiently servicing successively arriving data, and overall performance. Mechanisms for receiving and utilizing device user and/or receiver (e.g., base station) feedback are also disclosed. | 02-09-2012 |
